Although we do not use the reg->tp_scale I see no log which explains
that it will not, I'm reviewing TPC right now and we do need to
support it but its unclear to me yet if we are doing everything
correctly in mac80211 / cfg80211 for it. As far as I can see the
tp_scale stuff is used only if the default is not set, but as you
noted its always set to the default. I am trying to review the
internal code to see under what cases this changes but its hard to
review. Although I'd like to see this removed I'd prefer to treat this
separately from the cleanup you are doing, which I do find highly
valuable.
